Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a top plate for furniture which is easy to replace and separate and is suitable for recycling.

[0002]

2. Description of the Related Art A top plate used for furniture such as desks, tables and desks has conventionally been made of a thermosetting resin decorative plate such as a melamine resin decorative plate excellent in surface finish and surface hardness. In many cases, it is manufactured by fixing it to a steel plate or wooden top plate body with an adhesive or the like.

[0003]

However, in such a case, it is difficult to separate and dispose of the upper surface material because the upper surface material is adhered to the main body of the top board with an adhesive. There is also a problem that the solvent-based adhesive is difficult to discard as it is. Further, in such a case, it is difficult to replace the upper surface material, and when a material that is difficult to recycle such as melamine resin is used, there is a problem that the environmental load at the time of disposal and the cost become very high.

[0004]

In view of the above problems, the present invention provides a melamine resin decorative board and an adhesive agent which are easy to separate and dispose of the upper surface material and the top plate body and are suitable for recycling the material. It was decided not to use it, but to construct a top plate that has a low environmental load and low cost.
